主　　题：Bell states superconducting charge qubit two-qubit logic gate nanomechanical resonator 

摘      要：We propose a scheme for generating Bell states involving two SQUID-based charge qubits by coupling themto a nanomechanical *** also show that it is possible to implement a two-qubit logic gate between the twocharge qubits by choosing carefully the interaction time.
